Funny elec problem /Patrol

Sounds like a bad earth, easy fix.

Derek is probably right, but a couple of questions to confirm.

1. Do both front & back turn indicators come on with the headlight?

2. Is the left headlight coming on at reduced power?

If yes to both then it certainly is an earth return connection fault. The left headlight and left front indicator must be sharing the same connection to chassis and this connection is poor. Trace the earth return wire from your left headlight to the point where it connects to the chassis. Remove the connection and clean it then remake the connection firmly. The earth return wire from the headlight may be enclosed within a loom but if you follow the loom a little you may find a wire leaving the loom to connect to chassis.

If all else fails, identify the earth return wire at the headlamp and connect a wire to it, then connect this new wire to a good earth point on the body/chassis.

Check your trailer plug wiring. (If fitted)

I had a similar problem in my GQ Patrol. Replaced the indicator/light switch...problem solved for a few months, then it reappeared.
Took it to my local Auto Sparky...he also replaced the above switch..but tweaked it slightly. He said to keep the receipt as the switches are notoriously fickle..and I had a years guarantee on the job he did.

So I take it as a MK... or is it a GU.... maybe a GQ?

Year made or model goes along way to obtaining information.

That could well be an earthing problem !

Try and locate the main earth, from the battery, remove it and scratch up the metal alll around the bolt and the nut it attatches.

OR

Get another earth strap, that can bolt to the motor, with enough length to allow for flex when the motor torques up, and go directly from the battery's earth, (so you have 2 earths).

OR
Do both

assuming GQ series, combination switch for sure.... very common. Sold hundereds
